methods - 无法为签名“data.frame”、“character”找到函数“writeRaster”的继承方法

Question

我正在尝试从 data.frame 中保存 .csv 栅格文件，但发生错误。

library(dismo)
sp <- gbif("Neurergus ","kaiseri")   
sp <- sp[sp$basisOfRecord %in% c("HUMAN_OBSERVATION", "OBSERVATION", "PRESERVED_SPECIMEN"), c("lon", "lat")]    
sp$species <- 1   
sp <- na.omit(sp)

writeRaster(spg, "zzz.csv")

#Error in (function (classes, fdef, mtable)  : 
#  unable to find an inherited method for function ‘writeRaster’ for signature ‘&quot;data.frame", "character"’

Answer 1

您想将 a 写入data.frame文件.csv。你应该使用write.csv它。

write.csv(spg, "zzz.csv", row.names=FALSE)

writeRaster用于写入栅格数据。
